Thought of giving this brand made in US a try as is organic but was very disappointed that the quality is poor and impure when I did a simple test by dissolving in water. Very slow to dissolve and when did the mixture look dirty green and cakey. I will stick to my usual 100% from Japan chlorella which dissolve nicely into a beautiful green fine mixture like freshly extracted. Some poor quality and environmentally contaminated chlorella are imported from Taiwan, Indonesia or China into Japan as Made-in-Japan. Good Chlorella is helpful in maintaining healthy body which I have been consuming for years. Has to be careful when selecting. from Singapore
